@RiCkLaR, That makes sense. Thanks for the details. In my case, I was actually deliberately experimenting with it, as someone elsewhere was needing to know how to get back to the stock launcher, since Launcher Manager no longer worked for them with the latest Fire TV versions. That's what prompted me to do the following, to better understand the various moving parts: I deliberately ran the latest updates, and force reinstalled FireHomeStarterApplication apk. Then I tested out your method. Your explanation fits perfectly. I've actually been thinking about getting a different device, so I'm not worried about losing the custom launcher linked to the Home button for now.
